Description

Technical Field

[0001] This invention relates to the field of sectional sliding door technology, specifically a sectional sliding door with a buffer braking mechanism. Background Technology

[0002] Currently, the gates used at the entrances and exits of large venues such as squares, factories, and buildings are all horizontally opening and closing integral sliding doors or segmented sliding doors, which are helpful for opening and closing the entrances and exits of large venues such as squares, factories, and buildings.

[0003] If a full sliding door is used, the actual maximum opening width can only be half the width of the site opening. The other half of the width needs to be reserved for storing the door when it is open, which is not conducive to opening the entrances and exits of large places such as squares, factories, and buildings. Sectional sliding doors can better open the entrances and exits of large places such as squares, factories, and buildings. Their opening width is greater than that of a full sliding door, which is helpful for use. Existing sectional sliding doors are not easy to buffer and stop when closing in an emergency, such as when someone rushes in. The lack of buffer and stopping when closing sectional sliding doors can easily pinch and injure people who rush in. If children or animals play or stop in the closing path of sectional sliding doors, the lack of buffer and stopping when closing sectional sliding doors can also cause pinching and injury to children or animals. Therefore, sectional sliding doors are not conducive to the use of sectional sliding doors.

[0004] Therefore, we propose a segmented sliding door with a buffer braking mechanism. Summary of the Invention

[0005] In view of the problems existing in the above and / or existing sliding doors with buffer braking measures, the present invention is proposed.

[0006] Therefore, the purpose of this invention is to provide a sliding door with a buffer braking mechanism. By adding a buffer braking mechanism to the sliding door, the problems of the prior art mentioned above can be solved, such as the inconvenience of buffer braking when someone rushes in during an emergency, the difficulty of buffer braking when the sliding door closes, the risk of injury to a person rushing in, and the inability of buffer braking when children or animals play or stop in the closing path of the sliding door, which also causes injury to children or animals. These issues make the sliding door unsuitable for use.

[0007] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A sliding door with a buffer braking mechanism includes a sliding door body and a traction head at one end of the sliding door body.

[0012] As a preferred embodiment of the sliding door with buffer braking measures described in this invention, the ends of the telescopic hoses on the same side away from the arc-shaped rotating plate are connected by a U-shaped tube. The middle part of the U-shaped tube is arched upward. The middle parts of the upper ends of the U-shaped tubes are connected by a first connecting tube.

[0013] As a preferred embodiment of the sliding door with buffer braking measures described in this invention, a second connecting pipe is connected to the upper side of the middle of the U-shaped tube on the side away from the infrared sensor. A water pump is installed on the side of the traction machine head near the second connecting pipe at the end of the second connecting pipe away from the U-shaped tube.

A telescopic hose 20, connected to the retention groove 11, is connected to the outer ring surface of the arc-shaped rotating plate 8 inside the spring 14. A vertically positioned electric telescopic rod 16 is installed at the center of the upper surface of the fixing block 15. The output end faces downward and extends through to the lower side of the fixed block 15. The output end of the electric telescopic rod 16 is fixedly connected to the middle of the upper surface of the pressure block 17.

[0032] Infrared sensor 3 is installed on one side of the traction head 2 at the corner of the end away from the middle of the sliding door body 1. The end of brush 13 away from the arc-shaped rotating plate 8 is in contact with the moving wheel 7.

The connecting block 18 can limit and fix the spring 14. The end of the telescopic hose 20 away from the arc-shaped rotating plate 8 passes through the middle of the connecting block 18 and extends to the upper side of the connecting block 18. The connecting block 18 has a matching slot for the telescopic hose 20.

[0033] On the same side, the ends of the telescopic hoses 20 furthest from the arc-shaped rotating plate 8 are connected to a U-shaped tube 19. The middle of the U-shaped tube 19 is arched upwards. The middle of the upper ends of the U-shaped tubes 19 are connected to a first connecting tube 21, which connects the U-shaped tubes 19. The first connecting tube 21 passes through both sides of the traction head 2. The upper side of the middle of the U-shaped tube 19 furthest from the infrared sensor 3 is connected to a second connecting tube 22. The side of the traction head 2 closest to the second connecting tube 22 is located at the second connecting tube. A water pump 24 is installed at the end of pipe 22 away from U-shaped pipe 19. The end of water pump 24 that outputs liquid is connected to the end of second connecting pipe 22 away from U-shaped pipe 19 and is in a connected state.

Mounting plate 25 can support and fix water tank 26, which can facilitate stable use of water tank 26.

[0034] The end of the water pump 24 that draws liquid is connected to a third connecting pipe 23. The end of the third connecting pipe 23 away from the water pump 24 passes through the mounting plate 25 and is connected to the lower surface of the water tank 26. The end of the third connecting pipe 23 away from the water pump 24 passes through the bottom of the water tank 26. The third connecting pipe 23 can connect the water pump 24 and the water tank 26. The third connecting pipe 23 is in a state of communication with the interior of the water tank 26. The upper end of the water tank 26 is open. The upper end of the water tank 26 is covered with a matching cover 27. The cover 27 can cover the opening at the upper end of the water tank 26 to prevent dirt or foreign objects from entering through the opening at the upper end of the water tank 26 and affecting its use. A handle 28 is fixed in the middle of the upper surface of the cover 27.

[0035] The working principle of this invention is as follows: During use, the sliding gate body 1 and the traction head 2 are installed at the entrance / exit of large venues such as squares, factories, and buildings where they are to be used. In use, the traction head 2 moves via the moving wheels 7 on its lower side. The moving wheels 7 can adjust the position of the traction head 2, allowing it to pull the sliding gate body 1 out or push it in, thus opening or closing the entrance / exit of the large venues. During use, as the moving wheels 7 rotate, the brush 13 on the inner ring of the arc-shaped rotating plate 8 continuously cleans the outer ring of the moving wheels 7, preventing dirt or foreign objects from adhering to the moving wheels 7 and affecting their normal movement of the traction head 2. This helps maintain the stability of the traction head 2's movement. When the adhering dirt cannot be swept away by the brush 13, the water pump 24 is turned on. With the water pump 24 turned on, the water pump 24 can draw water from the water tank 26 through the third connecting pipe 23. The mounting plate 25 can support and fix the water tank 26, making it easy to use the water tank 26 stably. The water pump 24 delivers the drawn water to the U-shaped pipe 19 through the second connecting pipe 22. The water delivered to the U-shaped pipe 19 can be delivered to another U-shaped pipe 19 through the first connecting pipe 21. The water entering the U-shaped pipe 19 can flow through both ends of the U-shaped pipe 19 into the telescopic hose 20 inside the spring 14. The water in the telescopic hose 20 will flow into the retention groove 11 on the arc-shaped rotating plate 8. The water entering the retention groove 11 can flow through the drain pipe 12 to the moving wheel 7 inside the arc-shaped plate 5 to rinse the moving wheel 7.

[0036] During the process of rinsing the movable wheel 7 with water flowing out of the drain pipe 12, the brush 13 on the inner ring surface of the arc plate 5 located between the drain pipes 12 can simultaneously clean the outer ring surface of the movable wheel 7, so as to remove dirt from the movable wheel 7 and help ensure normal use of the movable wheel 7. For example, after the water in the water tank 26 is used up, the cover 27 can be removed by the handle 28 to refill water through the opening at the top of the water tank 26. After refilling, the cover 27 can be returned to the opening at the top of the water tank 26 by the handle 28 to cover it. The cover 27 can cover the opening at the top of the water tank 26. The shielding and protection prevents dirt or foreign objects from entering the water tank 26 through the opening at the top of the water tank 26 and affecting its use. During the movement of the traction head 2, it can drive the infrared sensor 3 to move. During the process of the traction head 2 driving the sliding door body 1 to close, if there are children playing or pausing or animals pausing in the path of the traction head 2, the infrared sensor 3 can sense the children or animals playing or pausing. Or, when there is an emergency and someone rushes in quickly, the infrared sensor 3 will also sense it. The infrared sensor 3 can transmit the sensed signal to the PLC controller 4 that is electrically connected.

[0037] When the PLC controller 4 receives a signal from the infrared sensor 3, it controls the electric telescopic rod 16 to open, causing the output end of the electric telescopic rod 16 to pull the pressure block 17 upward. During this upward movement, the pressure block 17 releases its pressure on the arc-shaped rotating plate 8. Under the action of the spring 14 on the lower surface of the connecting block 18, the end of the arc-shaped rotating plate 8 fixedly connected to the spring 14 is pulled, causing the arc-shaped rotating plate 8 to rotate along the part rotatably connected to the arc-shaped plate 5. During this rotation, the fixed portion on the arc-shaped rotating plate 8... The connected locking block 10 moves toward the moving wheel 7 and enters the locking groove 9 on the moving wheel 7. The locking block 10 can lock and limit the moving wheel 7 through the locking groove 9, so as to buffer and stop the moving wheel 7. The buffer and stop of the moving wheel 7 by the locking block 10 and the locking groove 9 helps to stop the moving towing head 2, which can prevent the towing head 2 from pinching children or animals that are stationary or playing, and helps to prevent people who rush in quickly due to an emergency from being pinched by the movement of the towing head 2. It helps to ensure the safety of children or animals that are stationary or playing, as well as people who rush in quickly due to an emergency.

[0038] During use, it helps to buffer and stop the sliding door body 1 and the traction head 2, preventing people from being pinched when they rush in. It can also prevent children or animals from being pinched when they play or stop on the closing path of the sliding door body 1 and the traction head 2, thus facilitating the use of the sliding door body 1 and the traction head 2.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
